How to remove Vista OEM branding

If you don’t feel the need to be reminded of your computer manufacturer every time you use the System or Performance Information & Tools applets, copy the following (italicised) lines into a blank Notepad document and save to your desktop as RemoveBranding.reg. Then double-click the file and accept the prompts to permanently* remove your manufacturer’s name and logo.

If you’d also like to hide the logo from the Welcome Center, rename the oobe.xml file (which you will find in C:\Windows\System32\OOBE\Info) to something else, e.g. oldoobe.xml.

* In case you ever want to restore the System/Performance Info branding, you should first back up the relevant registry keys. To reinstate the Welcome Center branding, simply rename oldoobe.xml back to oobe.xml.
